To all whom it ma concern: I

Be it known t at I, WILLIAM A. Ams- WORTH, a citizen of the United States of America, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Dyeing-Machines; and '1 do hereby declare the following to be a full,

rate with liquid dye. The member which is saturated with dye may be of any suitable fabric material such as felt or the like. In practice it is desirable that this dye carrying member shall be movable so as to bring differentpoints of contact for the yarn as it is pressed thereagainst to receive the dye. One primary object of my invention is to provide a rotatable dye carrying member which carries a felt around the same adapted to be partially immersed in the dye, the axis of rotation of said dye carrying member being located so that a rotation thereof continually changes the position of the felt whereby, when the yarn is depressed into contact withthe felt itstrikes in different places thereon. This is desirable as otherwise the yarn would, in a short time, out through the felt and render it useless in operation. A further object of the invention is to provide means for continuously turnlng'sald dye carrying member durlng the o 'eration of the machine.

A still further ob ect of the invention is to provide the windin and dyeing machine and the dye carryln tube thereof with many novel features 0 construction and arrangement of parts for erforming the ran om dyeing of yarn'or ike material in the most effective manner without danger of'ends of the yarn becoming caught in the.

mechanism or of remaining in contact with the dye soaked felt should the yarn at any time break during the process of winding and dyeing. All of these features together with many others not at this time specifically stated, will appear fully and in detail as understanding of the invention is had from the following description taken in connection with the accompanying drawin in which;

igure 1 is a fragmentary partial section and end elevation showing so much of a winding and dyeing machine as is necessary for an understanding of the invention, which is applied thereto.

Fig. 2 is a fragmentary perspective view illustrating the principal Working parts for accomplishing the dyeing.

Fig. 3 is a fragmentary enlarged plan View showing one unit of the dyeing mechanism; and

Fig. 4 is a transverse section therethrough.

Like reference characters refer to like parts in the different vieWs of the drawing.

The usual winding machine used in knitting factories includes frame parts 1 and 2, as shown in Fig. 1, and a plurality of vertical spindles 3 are mounted for rotation in the length of said frame each carrying a cone 4 at its upper end on which the yarn, thread or like material 4 is wound. The yarn passes from acone 5 to the receiving cone 4, the spindles being driven in any suitable manner as by a belt around the pulley 6 thereon. The yarn passes over a p n 7 projecting from a nut 8 which is threaded on a rod 9, the same also being rotatably mounted and periodically reversed in its movements so as to carry the guide 10 up and down lengthwise ,of the cone 4 for properly winding the yarn thereon. All of this construction is old and well knoWn-a'nd'is fully shown in my prior patent to which reference has been made.

The yarn as it passes to the cone 4 runs above a cylinder 11 in which a quantity of liquid dye is placed. I This cylinder is carried by suitable brackets 12 attached at one edge of the frame member 1. Brackets 14 are secured to the cylinder 11 and carry tension devices 13 at their outer ends, the yarn passing therethrough and thene across the dye cylinder and under a guide roller 15 the same. It is, of course, understood that the description made refers to one unit only located and secured at its'ends to the plate 17 adjacent the ends of the slot. A short post 20 is attached to the plate 17 and projects upwardly therefrom a short distance to one side of the normal path of movement of the yarn P.

A stirrup 21 is inserted into the cylinder at each opening 16 the upper ends of the sides thereof being hooked to connect with the sides of the opening 16 as shown in Fig. 4. A shaft-22 is rotatably mounted at its ends in and extends between the sides of the stirrup. Qn this shaft a roller is secured around which two ringsof felt are placed and attached. Said rings of felt extend upwardly through the slot 18 and the wire 19 passes between same. The dye in the cylinder 11 is kept high enough so that at least the lower parts of said felt members immerse therein.' A gear 24 is fixed on the shaft 22 and is in mesh with a spiral gear 25 fixed on a shaft 26 which extends the full length of thecylinder 11 there being one of these spiral gears 25 on the shaft for each of the dyeing units, all turning with the shaft. One end of the shaft is equipped with a drive pulley 27 and may be" turned by means of a belt 28 leading to any suitable driving mechanism. Paralleling the cylinder 11 is a shaft 29 on which cam members 30 are secured so that one of the same lies above each of the horizontal portions of the yarn 4 as it passes from the tension 13 to the roller 15. This shaft has a pulley 31 at its end which may be driven by a belt 32. With each rotation of the shaft and with a oam of the form shown in Figs. 1 and 2 the yarn is twice depressed and brought into contact with the projecting portion of the felt 23 absorbing dye therefrom during the time that it is in contact therewith.

In operation the shaft 22 and attached parts are continuously turnin whereby the yarn 4 strikes each time at a different oint on the felt. This saves the felt from eing cut through b the yarn and greatly len thens the life of operation of said felts. he wire 19 reinforces the felts and holds the same from being carried to one side and at the same time insures a ainst an loose. end of any yarn' passing ownwar y through the slot 18 and becoming entangled with the mechanism and also insures against any such'loose endwinding around or being carried by the felts downwardly to the cylinder. This might occur in practice any time should the yarn or like material break during the operation of winding and dyeing.

Furthermore, the post 2 is of utility in that plicates be made for the several units in the length of the machine, this greatly reducing the cost of manufacture. The wire 19 keeps the felts free from cuts and with this construction a new felt may be put on at any time.

I have shown the axis of the shaft 22 parallel to the length of the yarn 4 but the invention is not.to be considered as limited thereto as it is obvious that; the angle of the shaft to the yarn may be widely varied. Various other changes may be resorted .to without departing from the invention which is defined in the appended claims and I, accordingly, consider myself entitled to all modifications of structure which fall within the scope of the claims defining the invention.

I claim:
